Abstract

L'invention concerne un procédé et un dispositif permettant d'initialiser une communication de paquets de données montante, d'un dispositif mobile à une station de base sur un canal sémaphore de paquets, celle-ci étant initialisée lorsque le dispositif mobile lit l'état de diffusion des canaux sémaphores de paquets, suite à quoi le dispositif mobile envoie un préambule d'accès à la station de base, accusé de réception par la station de base, puis le dispositif mobile envoie un préambule de collision auquel répond la station de base avec une réponse de collision correspondante. Si la réponse de la station de base au préambule de collision comprend également un message d'attribution de canaux, la station de base initialise alors une communication de paquets de données montante sur un canal attribué à condition que l'état de diffusion du canal attribué ait été préalablement libre. Cependant, si la réponse de la station de base au préambule de collision comprend un message d'attribution de canaux désignant des canaux dont l'état de diffusion n'ait pas été préalablement libre, la tentative d'accès du dispositif mobile est interrompue.
